Fig. A.7
Left: hardness (ratio of bands 9−20 keV/2−9 keV ) computed from RXTE-PCA data for the three observations of V4641 Sgr. Each point is the mean value of hardness and the error bar represents the standard error on the mean. Right: radio data for V4641 Sgr, from ATCA and VLA (Rupen et al. 2004b,a; Senkbeil & Sault 2004). RXTE-PCAand H.E.S.S. observation times are indicated by blue shaded bands.
